SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 600,439, dated March 8, 1898.

Application filed December 27,.189'7. Serial No. 663,647. (No model.)

To all toil/07m it may concern.-

Be it known that I, ALBERT A. MoRRETT, a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Shutter-lVorker, of which the following is a specification.

This invention relates to shutter-workers, its object being to provide a simple and efficient mechanism by which the latch of the shutter can be disengaged from the catch and the shutter opened or closed without necessitating the opening of the window.

\Vith this object in view the invention consists of the several details of construction and combination of parts, as will be hereinafter 'fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of a portion of a window-frame, looking from the -inside of the building, the sashes being removed, and showing the manner of mounting my improved shutter-worker, the shutter being closed and the window sill partly broken away. Fig. 2 is a horizontal sectional view. Fig. 3 is a detail View of the push-rod. Fig. at is a similar view of the tube. Fig. 5 is a detail view of the pivoted bar. Fig. 6 is a detail view of the elbow-lever.

Similar reference-numerals indicate similar parts in the several figures.

1 indicates the window-frame, 2 the sill, 3 the shutter, 4 the latch, and 5 the catch, all of which may be of any ordinary or approved construction. A tube 6 is supported in a horizontal hole formed in the window-sill and provided with a flange 7 near its front end to be secured to the inner edge of the sill. This flange may be integral with the tube or may be a separate part secured to it in any suitable manner. The end of the tube which projects beyond the flange inside the windowframe is provided with a threaded opening 8, which communicates with the bore of the tube, and a set-screw 9 works in this threaded opening for a purpose to be hereinafter referred to.

The tube is provided with a reversed spiral slot 10, extending from the flange 7 to near the other end of the tube, said slot starting from the flange to one side of the vertical center of the tube when the latter is in its proper positi0n,then extending spirally across the vertical center, when its direction is reversed to cause it to extend spirally in the opposite direction until it terminates at substantially the vertical center of the tube on the side opposite to where it started and near the outer end thereof. This slot can start from the under side of the tube and terminate on the upper side, or vice versa, as preferred.

A push-rod formed of two sections (indicated by 11 and 12) hinged together at 13 is supported in the tube 6. A curved arm 1. is rigidly connected to the outer end of the section 11, at a right angle thereto. This arm may be integral with the section 11 or be a separate part rigidly secured to it. The section 11 will be of such length that when the shutter is closed the arm 14 will be in close proximity to the shutter, and the inner end of the section will project sufficientlybeyond the tube to permit the section 12 to be folded down in a vertical position, as indicated in Fig. 1. The section 12 of the push-rod is provided at its free end with a knob 15, which will serve as a handhold for the operator. A pin 11 is secured to the section 11 of the push -rod and projects therefrom into the slot 10.

16 indicates a short bar pivoted at one end on a pin or screw 17, which is secured in the lower rail of the shutter, adjacent to the hinged edge of the latter. This bar will normally depend from its pivot in a vertical di- 8 5 rection, and to its lower end one end of a rod 18 is loosely connected, the other end of said rod being loosely connected to the free end of the short arm 19 of an elbow-lever. This elbow-lever is pivoted at its angle to the lower 90 rail of the shutter 011 a pin or screw 20, and the long arm 21 of the lever is loosely engaged with the latch at.

A lug or car 22 projects forwardly from the bar 16 below its pivot and is provided with 5 a vertically-disposed opening 23, through which the curved arm 14 extends loosely. A guide-bar 24 is secured to the shutter over the bar 16 in order to keep the latter in parallel relation to the face of the shutter dur- I00 ing its movement, but to permit it to oscillate freely on its pivot in the arc of a circle.

The several parts will be in their normal position when the shutter is closed, and the section 12 of the push -rod will be folded down in a vertical position. The pin 11 will be in the vertical center of the tube at the inner end of the slot, and the bar 16 will depend in a vertical position from its pivot,with the arm 14 extending upwardly through the opening 23. It, now, it be desired to open the shutter,the push-rod will be straightened out and given a short turn to the right, that part of the slot in the tube which extends at the inner end to one side of the vertical center of the tube permitting the pin to move in the slot sufficiently for this purpose. This slight movement will have the effect of rocking the bar 16 on its pivot sufficiently to-rock the elbow-lever and disengage the latch from the catch. By pushing on the rod the shutter will begin. to open, and in this outward movement the arm 14 will first turn toward the free end of the shutter, and the bar 16 will be oscillated on its pivot to follow the movement of the said bar,and in the further opening movement of the shutter the bar will return to its vertical position,when the shutter will extend out at substantially a right angle to the front of the frame, and in the further outward movement of the rod the arm 14 will describe a quarter-circle in a direction toward the hinged ends of the shutter, and the shutter will thus be thrown completely open. In closing the shutter the movement of the push-rod is reversed. It is given a short turn to the left and is then pulled inward. The spiral slot of the tube serves as a guide in the movement of the push-rod, and it is only necessary after disengaging the catch to slide the rod outward and draw it inward.

The opening of the shutter can be arrested at any desired point, and by tightening up the set-screw 9 it will be caused to engage with the push-rod and lock it against longitudinal movement in the tube, and thus lock the shutter in the desired position.

Having thus described the invention, what I claim is 1. In a shutter-worker,the combination with the shutter, of a horizontal tube rigidly supported in the window-frame and having a reversed spiral guide-slot, apush-rod supported in the tube to have longitudinal and axial movement therein, a pin on the push-rod projecting into said slot, and an arm on the end of the push-rod loosely connected to the shutter, substantially as and for the purpose speci fied.

2. In a shutter-worker,the combination with the shutter, of a horizontal tube rigidly supported in the window-frame and having a reversed spiral guide-slot, apush-rod supported in the tube to have longitudinal and axial movement therein, a pin on the push-rod projecting into said slot, an arm on the outer end of the push-rod, and a bar pivoted at its upper end on the shutter and having a projection provided with a vertically-disposed opening through which said arm extends loosely, substantially as described.

3. In a shutter-worker,the combination with the shutter and its latch, of a horizontal tube rigidly supported inthe window-frame and having a reversed spiral guide-slot, a pushrod supported in the tube to havelongitudinal and axial movement therein, a pin on the push-rod projecting into said slot, an arm on the end of the push-rod, a bar pivoted at its upper end on the shutter and having a projection provided with a vertically-disposed opening through which said arm extends loosely, an elbow-lever pivoted on the shutter with one arm loosely engaging the shutterlatch, and a rod connectingthe other arm of the lever and the lower end of said bar, substantially as described.

4. In a shutterworker,the combination with the shutter, of a tube rigidly supported in the window-frame and having a reversed spiral guide-slot, a push-rod supported in the tube to have longitudinal and axial movement therein, a pin on the push-rod projecting into said slot, an arm on the end of the push-rod loosely connected to the shutter, and a setscrew in the tube adapted to be engaged with the push-rod to lock the latter against movement in the tube, substantially as described.

5. In a shutter-worker, the combination with the shutter, of a tube rigidly supported in the window-frame and having a reversed spiral guide-slot, a push-rod formed of two sections hinged together, one of said sections and the hinge being outside the tube when the parts are in their normal position, whereby said section may be folded down vertically, a pin on the push-rod projecting into said slot, and an arm on the end of the push-rod loosely connected to the shutter, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ALBERT A. MORRETT.
